目的测量飞行员鼻声发射(acoustic rhinometry,AR)、鼻阻力(rhinomanometry,RM)正常值范围,分析双侧鼻腔的差异及两种结果之间的关系。方法应用英国GM公司A1型鼻声发射仪和NR6型鼻阻力仪测量41例健康飞行员的鼻腔最小截面积(minimum cross-sectional area,MCA),0-5cm、2-5cm的鼻腔容积(V5、V2-5),通过前鼻主动测压法测量鼻压差为150Pa时单侧或双侧鼻腔阻力的呼气相和吸气相单侧鼻腔吸气、呼气阻力及鼻气道总阻力(Rins150,Rexp150,Rins150T,Rexp150T)。结果 MCA右侧为(0.69±0.19)cm2,左侧为(0.57±0.20)cm2,平均为(0.63±0.20)cm2;V5右侧为(6.33±0.96)cm3,左侧为(5.64±1.00)cm3,平均为(5.99±1.03)cm2;V2-5右侧为(4.64±0.91)cm3,左侧为(3.96±0.92)cm3,平均为(4.30±0.97)cm2;Rins150右侧为(0.46±0.19)Pa/(cm2.s),左侧为(0.38±0.18)Pa/(cm2.s),平均为(0.42±0.18)Pa/(cm2.s);Rexp150右侧为(0.47±0.19)Pa/(cm2.s),左侧为(0.38±0.19)Pa/(cm2.s),平均为(0.42±0.19)Pa/(cm2.s);Rins150T为(0.20±0.08)Pa/(cm2.s),Rexp150T为(0.20±0.08)Pa/(cm2.s),以上两侧鼻腔及Rins150、Rexp150、Rins150T、Rexp150T间差异均无统计学意义。Rins150、Rexp150与MCA、V5、V2-5之间存在负相关性(P<0.05)。结论飞行员鼻阻力与鼻声反射之间具有相关性,所测值范围可为飞行员鼻腔通气状态评价提供依据。
Objective To measure the normal range of nasal acoustic rhinometry (AR) and rhinomanometry (RM), analyze the differences of bilateral nasal passages and the relationship between the two results. Methods The nasal minimum cross-sectional area (MCA), 0-5 cm, nasal volume of 2-5 cm (V5, V2) of 41 healthy pilots were measured by GM GM A1 nasal emitter and NR6 nasal resistance meter. -5), nasal resistance of unilateral or bilateral expiratory and inspiratory single nasal inspiratory, expiratory resistance and total nasal airway resistance (Rins150 , Rexp150, Rins150T, Rexp150T). Results The mean MCA was (0.69 ± 0.19) cm 2 on the left and (0.57 ± 0.20) cm 2 on the left, with an average of (0.63 ± 0.20) cm 2 for the MCA and (6.33 ± 0.96) cm 3 for the V5 and 5.64 ± 1.00 for the left cm3 with an average of (5.99 ± 1.03) cm2; the right side of V2-5 was (4.64 ± 0.91) cm3 and the left side was (3.96 ± 0.92) cm3 with an average of (4.30 ± 0.97) cm2; the right side of Rins150 was (0.46 ± (0.42 ± 0.18) Pa / (cm2.s) on the left and (0.38 ± 0.18) Pa / (cm2.s) on the left; (0.47 ± 0.19) (0.42 ± 0.19) Pa / (cm2.s); Rins150T was (0.20 ± 0.08) Pa / (cm2) . Rexp150T was (0.20 ± 0.08) Pa / (cm2.s), there was no significant difference in nasal cavity, Rins150, Rexp150, Rins150T and Rexp150T between the two sides. There was a negative correlation between Rins150, Rexp150 and MCA, V5 and V2-5 (P <0.05). Conclusion There is a correlation between pilots nasal resistance and nasal reflex. The range of the measured value can provide the basis for pilot nasal ventilation evaluation.
